Default Transmission tuning costs

Quick question does anyone have experience with getting an A8 GS transmission tune? About how much should it cost and lastly anyone have any recommendations for the NC/VA areas?

I've never heard of a transmission tune. Interested as these A8 transmissions are pretty clunky.

Dyno calibration - $750
HP Tuner credits - $200 (trans only)
Remote Tuning Device - $230

Total - $1,180
Add 200 more if you want the ECU tuned.

Highly recommend you reach out to BRC raceworks - LT platform specialist. His tuning made a night and day difference with my A8.
Also recommend you let him tune the car; you would be hard pressed to find a better tuner who knows more about these platforms anywhere, he is fair & honest.

if the trans is 17+ you also need to get the TCM unlocked. HPtuners provides this service for $200 if you mail it in.

Wouldn't a "Transmission Adaptives Reset and Relearn" essentially be a "tune?"

That's what I do to mine when it misbehaves.

Is that a process we as owners drivers complete? What's involved?
Thanks

This must be done either by the dealer or using a diagnostic tool such as Altel MK808BT. Option #2 can be done in your garage.

you wont tune a trans tcu unless the engine ecu is also tuned since the trans calibrations are based off the torque produced by the engine. they go hand in hand with each other
4 credits for ecu 50$ each
2 credits for tcu. 50$ each
unlock by hp tuners 200$ plus whatever labor the shop charges to remove it ship it receive it and reinstall it
tune cost by tuner
